WIRE-GALVANIZING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 423,995, dated March 25, 1890.

Application filed November 4, 1889.

T0 aZZ whom it may concern.-

Be it known that I, BELVILLE A. GRANT, a citizen of the United States of America, residing at Lockport, in the county of Will and State of Illinois, have invented certain new and useful Improvements in lNire Galvanizing Apparatus, of which the following. is a specification, reference being had therein to the accompanying drawings, and the letters of reference thereon, forming a part of this specification, in wl1ich- Figure 1 is a horizontal section of the galvanizing apparatus, taken on line 2 of Fig. 3 looking down. Fig. 2 is a perspective view of the galvanizing apparatus having a portion broken away to show interior parts; and Fig. 3 is a vertical section of Fig. 2, taken on line 1 looking rearward. Fig. 4 is a detail View of a modified construction.

This invention relates to certain improvements in a wire-galvanizing apparatus, which improvements are fully set forth and explained in the following specification and claim.

Referring to the drawings, B is the vessel or pan for holding the galvanizing material. This vessel is shown in this instance as being in the form of a half cylinder and having extending flanges at its upper side for supporting it in its brick case A, and also supported at its bottom on the longitudinal wall H, forming a partition between the flues D on either side of said vessel. This pan or vessel may be made in any other convenient form to answer the purpose, and may be constructed of plates like a boiler or of any suitable material, and is set centrally between the side walls A, so as to leave a space between it and the side walls on either side, forming flues D, extending from the fire-box R in front of said vessel to its rear end. Said fiues also extend to the entire heightof said vessel, so that the metal therein near the top will be heated as well as that in the lower part thereof. Said flues are separated from each other at the rear end of said vessel by means of a wall or partition K and have discharge-ports T T at their rear ends opening into the flue S immediately below and leading to a chimney for causing a draft and escape of the gas. These dischargeports are controlled by means of valvesVfor the purpose of regulating the draft in the Serial No. 329,199- (No model.)

fiues, and for causing more or less draft in one flue than the other in case more heat is needed at one side of the vessel than the other.

Immediately in front of the vessel B is a fire-box B, into which extends an oil-burner L, that may be of any form or pattern necessary for the purpose, to which burner crude petroleum-oil is fed from pipe P, leading from a suitable adjacent receptacle. Said fire box It extends upward to the full height of the vessel B at its forward end and connects with the said side fluesD D at their forward ends. By having the said fire-box and fines the entire height of the vessel B the fire reaches to the top of the vessel at its ends and sides, where it is most necessary, as the metal in the vessel is most difficult to heat and keep in a molten state at its top. The floor or grate E of said fire-box is provided with the apertures W for admitting air to the fire-box to assist or cause ignition of the oil. a are similar air-inlets for admitting air to the flues for causing ignition of gas at and near their rear ends for heating the rear part of the vessel B, and e are apertures for looking into the fire-box.

P is a steam-pipe connected at its outer end with the burner L and leading from a steamboiler for admitting a steam-blast into the burner to drive and spray the oil forward into the fire-box. Said steam-pipe on its way from the boiler passes through one of the fines D at the side of vessel B, so as to be heated to a high degree for the purpose of superheating the steam before it reaches the oil in the burner, as it is better to use dry superheated steam for the blast than steam directly from the boiler not superheated. In this instance a superheated steam-blast pipe is shown as connected with the burner L; but I do not wish to be confined to the use of a steam-blast for that purpose, my idea being simply to use any kind of a blast to spray or deliver the oil into the furnace.

The front end of the vessel B next the firebox. is protected by brick-work, which extends around the corners of the vessel, and may be extended for some little distance along its sides for protecting that part of the vessel from injury from the fire, as shown in'Fig. at.

The outer brick walls of the apparatus are held to the brick wall by means of the vertical bars J and tie-rods r.

C C are air-inlets leading into the ash-pit. All these air-inlets and draft-holes are intended to be opened or closed by inserting some object, such as a brick.

By means of such construction of furnace and the use of crude oil for fuel a much more regular and even degree of heat can be maintained at less cost than by use of other fuel, as coal, and the galvanizing material kept at a uniform degree of heat, and the heat can be directed and applied to either side or to any part of the vessel in order to preserve such even and uniform heat of the galvanizin g material.

Having thus described my invention, What I claim as new, and desire to secure by Let ters Patent, is as follows, to Wit:
